DOOR-FASTENING.

SPECIFICATION forming part of Letters Patent No. 432,178, dated July 15,1890.

Application filed March 25, 1890. Serial No. 345,192. (No model.)

To all whom it may concern.-

Be it known that I, ANTON BRUNNER, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Door-Fastenings; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objectof this invention is to produce an improved safety-fastenerfor a door comparatively inexpensive in construction, neat inappearance, and efiective in operation, and which will serve as asupplemental look ing device when the door is closed.

The invention consists in the improved door-fastener and the combinationand arran gement of parts thereof, as hereinafter described, and finallyembodied in the claims.

Referring to the accompanying drawings, in which corresponding partsindicate similar parts in each of the several figures, Figure 1 is a topplan view of my improved door-fastener as applied to a closed door. Fig.2 is a side View of the same, the door and door-jamb being shown insection, and Fig. 3 is a side view with the door open.

In said drawings, a indicates a plate adapted to be secured to the door,screw-holes bbeing provided for the purpose, and carrying arms 0 c,firmly and rigidly secured thereto and extending substantially parallelwith the face thereof. Said plate is also provided with a keeper (Z,pivoted thereto between the front end thereof and the shoulders e ofsaid arms, as shown in the drawings.

A plate a is adapted to be secured to the door casing or jamb,screw-holes being provided for the purpose, and carrying a barf, one endof which is pivoted or hinged to said plate at g, the hinge-pin passingthrough a lug or post 71, projecting from said plate for the purpose. Tothe opposite end of said bar f is pivoted or hinged a bar 1', providedat its free end with arms j, extending laterally in opposite directionstherefrom, as shown.

The operation of the device is as follows,

to wit: The plates a and a being secured to the door and door-casing,respectively, the bar v is extended until the laterally-extending armsjthereof pass over the ends of the arms 0 0, thus permitting the bars fand t' to lie and work between said arms 0 c, as indicated in Figs. 1and 2. This being done, as the door is opened the said bar 2 is drawntoward the front edge of the door, the laterallyextending arms j passingbeneath the arms a 0 until they abut against the shoulders 6, thuspermitting the door to open from four to six inches and no further, aswill be understood upon reference to Fig.8. The keeper d, when turnedacross the bar f, as indicated by dotted lines in Fig. 1, serves to holdthe latter in position and to prevent the door from being opened fromthe outside in case the door should be left unlocked, as will bemanifest.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is

1. A safety-fastener for doors, consisting of a plate adapted to besecured to a door and carrying arms 0 and a plate adapted to be securedto the door-casing and carrying bars f and t hinged to one another, theformer hinged to said plate and the latter providedwithlaterally-extending arms 7', said parts being arranged in relation toeach other and operating as described, and for the purposes set forth.

2. A safety-fastener for doors, consisting of a plate adapted to besecured to a door and carrying arms 0, a plate adapted to be secured tothe door-casing and carrying bars f and c' hinged to one another, theformer hinged to said plate and the latter provided withlaterally-extending arms j, and also a keeper pivoted to the door-plate,as shown, said parts being arranged in relation to each other andoperating as described, and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7 th day of March, 1890.

ANTON BRUNNER.
